My wife and I are just passed the half way point in our two week Mexico vacation. We spent the first week in Oaxaca City, a favorite place of ours. But we, also, enjoy going to the beach and viewing the ocean. Therefore, we always end up in Huatulco on the Pacific Ocean. This is an area of multiple beaches and guaranteed hot weather. The days are in the high 80's, so warm but not overwhelming.
Yesterday we went snorkeling, with mixed results and satisfaction, but we did see lots of very colorful and, to us, unusual fish. Cab rides are cheap and here is a shot we took, from an observation point, on the way to the beach. It gives an idea of the beauty of the coastal area.
